stop()ing

Sonidores,

Does it make sense that you can't call stop() twice? Since it takes an 
argument indicating a time in the future, to update that time, you'd 
want to call it again.

For example, what if you have created a nice 5-second release on a sound 
using gain ramps, and when you started the release, you set the stop 
time on a node for 5 seconds in to the future. Then something occurs and 
you want to stop the sound immediately. Currently you cannot call stop() 
again with an updated shorter time *(*in fact, stop() simply fails 
silently in this case currently).

Thanks,
